However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0042] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0043] Figure 1 It is a schematic diagram of a safety warning device for inspection of mine excavation engineering; Figure 2yes Figure 1 The above schematic diagram is not an actual scale of the actual product.

[0044] like Figure 1 and Figure 2 As shown, the mine excavation engineering inspection safety warning device of the embodiment of the utility model includes: a bracket 1, a lamp holder 2, a bulb 3, an upper lampshade 4, a lower lampshade 5 and a vibrator 6.

[0045] The main function of the lamp holder 2 is to fix the position of the bulb 3 and provide an interface for connecting to the power supply to ensure that the current can be safely and stably transmitted to the bulb 3, thereby lighting the bulb 3. Its structural design must meet electrical safety standards to ensure good contact and durability. The lamp holder 2 usually has one or more fixing points for connecting it to the bracket 1. This can be a screw hole, a buckle, a threaded interface, etc., to ensure that the lamp holder 2 is stable and does not shake.

[0046] The inside of the lamp holder 2 is provided with a metal sheet or spring sheet connected to the bottom contact of the bulb 3. These contacts ensure the stability and conductivity of the electrical connection. Common types include screw-type lamp holders 2 such as E27 and E14, or plug-in lamp holders 2 such as GU10 and G9. The contact design of each type of lamp holder 2 is different.

[0047] For safety, insulating materials such as plastic or ceramic are usually used inside and outside the lamp holder 2 to prevent electric shock and short circuit. The insulator isolates the current and protects the user from electric shock when replacing the bulb 3.

[0048] The lamp holder 2 usually has one or more holes or terminals for connecting the power cord. These holes or terminals are designed with screws or clips to facilitate the fixing and connection of the wires.

[0049] The light bulb 3 is designed to achieve efficient and stable lighting effects and is mainly used in various environments such as homes, offices, and industrial sites. The function structure of the light bulb 3 usually includes the following key parts:

[0050] Glass tube: The outer shell of the bulb 3, usually made of transparent or milky white glass, protects the internal structure, isolates the external environment, and allows light to pass through. For LED bulbs 3, the outer shell may be made of acrylic or aluminum alloy materials to improve durability and heat dissipation performance.

[0051] Electrodes: Located at both ends of the bulb 3, they are responsible for conducting electricity, starting and maintaining the discharge process in the bulb 3. The electrodes of traditional fluorescent bulbs 3 contain substances that emit electrons, while LED bulbs 3 rely on PN junctions in semiconductor materials to conduct electricity.

[0052] Luminescent material: For the fluorescent bulb 3, a layer of fluorescent powder is coated inside, and when the ultraviolet light generated by the discharge shines on the fluorescent powder, it will be converted into visible light. The LED bulb 3 directly uses the light emitted by the LED chip, which is usually white light.

[0053] Gas: A conventional fluorescent bulb 3 is filled with a small amount of mercury vapor and an inert gas (such as argon) to form an arc discharge between electrodes, while an LED bulb 3 does not need to be filled with gas to emit light.

[0054] Connect the bulb 3 to the lamp holder 2 so that the electrode of the bulb 3 is connected to the contact point of the lamp holder 2. When the bulb 3 is powered on, it will emit light.

[0055] In mining projects, the sources of power supply mainly include the following aspects:

[0056] Power supply from mining substation or main step-down substation: This is the most common way of power supply. Mines usually have one or more substations, which connect high voltage electricity (such as 110kV or 35kV), step down the voltage to a voltage level suitable for mine use (such as 6kV, 10kV) through a transformer, and then distribute it to various power consumption points.

[0057] Self-provided power stations: For some large mines that are remote or not covered by the power grid, they may build their own power plants (such as coal-fired, oil-fired or hydroelectric power stations) to ensure a stable power supply. These power stations can flexibly adjust the power generation according to the actual power demand of the mine.

[0058] Dual-circuit power supply system: In order to ensure the continuity and reliability of mine power supply, the mine power supply system is often designed with at least two power supply lines. These two circuits are provided by different substations or power supply points. Even if there is a problem with one line, the other line can immediately take over the power supply to ensure the uninterrupted operation of mine production and safety facilities.

[0059] Emergency backup power supply: including diesel generators, UPS (uninterruptible power supply) systems, etc., used to provide temporary power when the main power fails, ensure the operation of key equipment such as ventilation, drainage, communication and security monitoring systems, and prevent safety accidents caused by power outages.

[0060] The connecting post on the lamp holder 2 is connected to the power supply through a cable to provide a continuous supply of electric energy for the light bulb 3 to emit light.

[0061] The lampshade can protect the bulb 3 or the lamp tube from external impact and dust pollution, and prolong the service life of the lamp. The lampshade is made of a wide range of materials, including but not limited to glass, acrylic, PC, PPC, PVC plastic and other transparent materials. Different materials give the lampshade different textures and light transmission properties.

[0062] The lampshade is usually fixed on the lamp holder 2 and can be easily installed and removed by means of screws, buckles, magnets, etc.

[0063] In a preferred embodiment, the lampshade includes an upper lampshade 4 and a lower lampshade 5. The upper lampshade 4 is mounted on the lamp holder 2; the upper portion of the lower lampshade 5 overlaps with the lower portion of the upper lampshade 4 with a gap therebetween; the bulb 3 is covered inside by the upper lampshade 4 and the lower lampshade 5.

[0064] Specifically, the upper lampshade 4 includes an upper straight wall portion 41, an arc-shaped upper connecting portion 42 and an upper hook portion 43; the top end of the upper straight wall portion 41 is connected to the lamp holder 2, the bottom end of the upper straight wall portion 41 is connected to one end of the upper connecting portion 42, and the other end of the upper connecting portion 42 is connected to the bottom end of the upper hook portion 43, so that the free end of the upper lampshade 4 is an upwardly bent hook-shaped structure.

[0065] The upper straight wall portion 41 is a standard cylindrical structure, the cross section of the upper connecting portion 42 is a semicircular, and the upper hook portion 43 is a standard cylindrical structure. The arc of the upper connecting portion 42 protrudes downward and is arranged on the inner side of the upper straight wall portion 41. The bottom end of the upper straight wall portion 41 is connected to one end of the upper connecting portion 42, and the bottom end of the upper hook portion 43 is connected to the other end of the upper connecting portion 42, so that the upper straight wall portion 41 and the upper hook portion 43 form a concentric structure.

[0066] The lower lampshade 5 includes a lower cover body 51, an arc-shaped lower connecting portion 52 and a lower hook portion 53; the top end of the lower cover body 51 is connected to one end of the lower connecting portion 52, and the other end of the upper connecting portion 42 is connected to the top end of the lower hook portion 53, so that the free end of the lower lampshade 5 is a hook-shaped structure bent downward; the upper hook portion 43 is arranged between the outer wall of the lower cover body 51 and the lower hook portion 53, and a gap is left.

[0067] The lower cover body 51 is a cylindrical structure with a closed bottom. The cross section of the lower connecting portion 52 is semicircular. The lower hook portion 53 is a standard cylindrical structure. The arc of the lower connecting portion 52 protrudes upward and is arranged on the outer side of the lower cover body 51. The top end of the lower cover body 51 is connected to one end of the lower connecting portion 52, and the top end of the lower hook portion 53 is connected to the other end of the lower connecting portion 52, so that the lower cover body 51 and the lower hook portion 53 are in a concentric structure.

[0068] The upper hook 43 is disposed between the lower hook 53 and the lower cover body 51, and a gap is left between the upper hook 43 and the lower hook 53 and the lower cover body 51. After installation, the height of the upper lampshade 4 is much smaller than the vertical distance from the top of the upper lampshade 4 to the bottom of the lower lampshade 5.

[0069] The vibrator 6 is installed on the bracket 1 , and the output end of the vibrator 6 is connected to the lower lampshade 5 . The vibrator 6 can drive the lower lampshade 5 to vibrate, and the accumulated dust attached to the surface of the lower lampshade 5 can be shaken off.

[0070] The vibrator 6 is installed on the bracket 1 and connected to the lower lampshade 5. It can effectively vibrate the lower lampshade 5 and automatically remove dust accumulated on the surface of the lampshade using the principle of physical vibration, thereby reducing the frequency of manual cleaning and improving maintenance efficiency and long-term use of the lamp.

[0071] The gap design reserved between the upper hook portion 43 and the lower cover body 51 and the lower hook portion 53 can reduce the vibration of the upper lampshade 4, the lamp holder 2 and the bulb 3, thereby avoiding the loosening of the connection structure, which is beneficial to the stability and safety of the device.

[0072] Due to the existence of the above-mentioned gap, although the route from the outside into the lampshade becomes tortuous, which is not conducive to the entry of dust, there is still a possibility of dust entering. In long-term use, especially in a harsh environment such as a mine excavation project, dust is likely to enter the lampshade. Therefore, a brush 7 is provided in the gap between the upper lampshade 4 and the lower lampshade 5.

[0073] In a preferred embodiment, the brush 7 is bonded to the lower lampshade 5. Specifically, the brush 7 is bonded to the lower hook 53, the lower connecting portion 52, and the position of the lower cover body 51 corresponding to the lower hook 53. The upper hook 43 is inserted in the middle of the brush 7.

[0074] There are usually several methods for bonding the brush 7 to the lower lampshade 5. For example: 1. Use the brush 7 to evenly apply a suitable adhesive (such as epoxy resin glue, silicone or special plastic glue) to the lower lampshade 5 or the part where the brush 7 needs to be fixed, and then stick the brush 7 on it, and keep the pressure until the glue solidifies; 2. If the material of the brush 7 allows, use a hot melt glue gun to melt the hot melt glue strip and apply it to the lower lampshade 5 or the base of the brush 7, and quickly stick and fix it, which is suitable for quick installation.

[0075] This is an innovative self-cleaning design by having a brush 7 built into the tiny gap between the upper and lower lampshades 5. The brush 7 can function as a passive cleaning element by the vibration of the lower lampshade 5.

[0076] The inclusion of the brush 7 shows attention to detail and is intended to address the problem of accumulation of fine particles here, which are often difficult to reach with conventional cleaning.

[0077] When the lower lampshade 5 vibrates, the brush 7 can effectively remove or block dust from entering the interior of the lamp, reducing dust accumulation, thereby reducing the frequency of regular deep cleaning.

[0078] The brush 7 acts as a buffer isolation layer, effectively preventing the upper lampshade 4 from making direct physical contact with the lower lampshade 5 during the vibration process. When the vibrator 6 drives the lower lampshade 5 to vibrate, even if the lower lampshade 5 is displaced to a certain extent, the presence of the brush 7 can ensure that a small and stable gap is maintained between the two, thereby avoiding hard collision. This design greatly reduces the wear and tear that may be caused by collision, prolongs the service life of the lampshade, and eliminates potential collision noise, making the lamp run more smoothly and quietly.

[0079] Direct collision will not only produce noise, but may also cause deformation or even damage to the lampshade, affecting the uniform distribution of light and the overall lighting effect. The setting of the brush 7 effectively alleviates this risk, protects the optical design and structural integrity of the lamp, and ensures the lighting quality and aesthetics of long-term use.

[0080] During the vibration cleaning process, the brush 7 can not only reduce collisions, but also use its own flexible structure to perform secondary cleaning of fine dust accumulated on the inner side of the upper lampshade 4 or the outer side of the lower lampshade 5 when the upper and lower lampshades 5 are in slight contact, thereby further improving the cleaning efficiency, making it difficult for dust to accumulate inside the lamp, and maintaining the light transmittance and lighting efficiency of the lamp.

[0081] The isolation effect of the brush 7 is particularly critical in dusty mining projects and slightly vibrating environments. It reduces the impact of external environmental factors on the interior of the lamp, enhances the stability and reliability of the lamp under harsh conditions, and is suitable for more diverse application scenarios.

[0082] In a preferred embodiment, a pressure sensor 8 and a controller are further included; the pressure sensor 8 is arranged between the lower lampshade 5 and the vibrator 6, and the pressure sensor 8 is connected to the controller; the controller is connected to the vibrator 6. The controller is connected to the power supply mentioned in the above embodiment, and provides a stable power supply required for the controller and the pressure sensor 8 connected to the controller.

[0083] The pressure sensor 8 can be fixed to the outside of the lower lampshade 5 by bonding, and at the position connected to the vibrator 6, to ensure that it can accurately sense the pressure change of the lower lampshade 5 on the vibrator 6. The sensor is connected to the controller through a wire or wirelessly, and the controller then establishes a control loop with the vibrator 6.

[0084] The pressure sensor 8 monitors the pressure change applied by the lower lampshade 5 to the vibrator 6, and then identifies the amount of dust accumulated on the outer surface of the lower lampshade 5. When the pressure is greater than the preset pressure, it indicates that the amount of dust accumulated on the outer surface of the lower lampshade 5 has reached the preset amount, and the pressure data is transmitted to the controller in real time. The controller intelligently adjusts the output time and strength of the vibrator 6 according to these data to avoid damage to the lamp structure caused by excessive vibration, while ensuring sufficient cleaning effect. By accurately controlling the operation of the vibrator 6, ineffective or excessive energy consumption is avoided, and the purpose of energy saving is achieved. In particular, during periods when cleaning demand is not high or in a state where it has been cleaned, the system can automatically reduce the vibration frequency or suspend work. Intelligently adjusting the vibration time and intensity, timely protective measures effectively extend the service life of the entire lamp system, including the vibrator 6, the lampshade and other components, reducing maintenance costs and replacement frequency. And when the pressure sensor 8 detects abnormally high pressure (such as the lampshade is pressed by foreign objects), the controller can immediately reduce or stop the operation of the vibrator 6 to prevent possible mechanical damage, thereby increasing the safety and reliability of the system.

[0085] In a preferred embodiment, an explosion-proof cover 9 is added, which is connected to the lamp holder 2 and covers the upper lampshade 4 and the lower lampshade 5. The explosion-proof cover 9 is a standard cylindrical structure. The explosion-proof cover 9 is a hollow metal mesh cover, which is usually made of corrosion-resistant materials such as high-strength cast aluminum or stainless steel, which have good mechanical strength and impact resistance.

[0086] The explosion-proof cover 9 can be fixed to the lamp holder 2 by threads, buckles or screws to ensure that the explosion-proof cover 9 and the lamp holder 2 are well sealed and not loose. After installation, carefully check whether all connection points are tightened and the seal is intact, and then turn on the power supply under safe conditions to test whether the lamp works normally.

[0087] In one embodiment, the bracket 1 includes an upper bracket 11 and a lower bracket 12 which are connected to each other; the lamp holder 2 is mounted on the upper bracket 11 ; and the vibrator 6 is mounted on the lower bracket 12 .

[0088] The support 1 is used to support the entire structure and ensure the stability of the structure. The specific structure and shape are not limited. Those skilled in the art can choose according to actual needs and available materials.

[0089] In this embodiment, it should be noted that the bracket 1 is made of a hollow steel pipe, and the cables required for the device are inserted into the hollow steel pipe.

[0090] The solution of using a hollow steel pipe as the bracket 1 and having built-in cables has the following beneficial effects:

[0091] Protect cables: Hollow steel pipes provide a physical protective barrier for cables, which can effectively prevent cables from external mechanical damage (such as extrusion, scratching, etc.) and environmental factors (such as moisture, corrosion, etc.), thereby extending the service life of cables.

[0092] Beautiful and neat: Hiding the cables inside the steel pipe makes the entire device look neater and more orderly, improving the overall aesthetics of the installation environment.

[0093] Convenient wiring and maintenance: The hollow steel pipe provides a convenient channel for the insertion of cables, which facilitates wiring operations during installation.

[0094] Improved safety: The wires are hidden inside the steel pipe, which can reduce the risk of electric shock and improve the safety of the place of use. This design is especially important for industrial environments that are susceptible to moisture or chemical corrosion.

[0095] Structural strength and stability: Steel pipe, as the material of bracket 1, has good mechanical properties and can provide sufficient support and stability to ensure that the lamp is firmly installed and is not easily deflected or collapsed due to external forces.

[0096] Space saving: The space of the bracket 1 itself is used to hide the cables, thus avoiding the use of additional cable management equipment or cable ducts, saving installation space, and being particularly beneficial for environments with limited space.

[0097] In summary, the design of using a hollow steel tube as the bracket 1 and having built-in cables not only improves the safety and protection level of the cables, but also takes into account aesthetics, practicality and ease of maintenance. It is an efficient and practical solution in modern lighting design.
